Weed Control Programs for Spring and Summer:

Summer weeds or Winter weeds can get out of control without proper management.


By April, spring application of preemergent herbicides for the control of summer annual weeds should have been applied.  However, if they have not been applied, application of a preemergent herbicide at this time will still control a majority of the summer annual weeds.  Application of preemergent herbicides should be used on St. Augustinegrass and centipedegrass lawns with caution in the spring.  While these herbicides are selective for turfgrasses, they can cause root pruning in these particular grasses, especially if they are under stress.  Also, bermudagrass and/or zoysiagrass areas that were not watered during the winter months should be treated with caution. 


The summer grassy and broadleaf weeds are just starting to appear in turfgrass sites.  For the broadleaf weeds, use one of the two-way or three-way hormone herbicide combination products.  For grassy weeds, use one of the herbicides containing MSMA or DSMA.  Note, for the arsenical herbicides to work, daytime temperatures need to be in the upper 80 to lower 90 degree F.  range.  For hard to control grassy weeds such as dallisgrass, it will probably take 2 to 3 applications applied at a 7 to 10 day interval.  It is very important to not water or mow the turfgrass for at least 24 and preferably 48 hours after treating with one of the arsenical herbicides.  Note, remember that the arsenical products such as MSMA and DSMA cannot be used on St. Augustinegrass or Centipedegrass lawns.




Listed below are several herbicide lists.  While these are partial lists, they do contain some of the more common herbicides used for weed control in turfgrass areas.  It is the buyer’s responsibility to read the herbicide label carefully before purchasing the product to make certain it is 1) still labeled for use on the weed they are trying to control and 2) and for the site ( residential lawn vs. sports field vs. sod farm, etc.)  and 3) the particular turfgrass species and variety they are treating.  Always read the label carefully before applying the herbicide to make sure the correct rate is being applied for effective weed control.


These lists are were formulated in April, 2006, as a resource list for  herbicide recommendations.  These will change from year to year.
